Yes

While you are taking her back to Woocott Institute you talk about the night before. She says that the sex was great but she doesn't know what came over her as she usually goes on a few dates before sex. You tell her you understand if she wants this to be short term. You drop her at her dorm and hurry back to the cottage to pick up your friends.

You should have been able to cum in her the first time as well as the second with risk of pregnancy. What neither of you knew was that someone had mixed something into many of the bottles that made that girls horny. It also made them more fertile. She had a few drinks at the cottage that contained the doctored liquor which is strong enough to reverse her birth control.

She tells you about her pregnancy six weeks after the party and that you're the daddy. She considered an abortion but can't really kill anything. She has to quit the tennis team and drop out of college. She is also concerned about the pictures and footage of the first time you two fucked. You tell her most of the "shoot" was fake and at her request erase and destroy what is left.

You and her decide to be a couple for the sake of your kids (she has triplets, 2 boys and a girl). Her parents at first hate you but come around after the kids are born. Your mother is also pissed at first but comes around after she sees how serious you and Erica are. You start working for your uncle near full-time. All the strain of work and new relationship and first-time unplanned pregnancy actually strengthens you and Erica.
